As long as you don't open contracts and don't operate recklessly, just buy mainstream coins, and you won't face liquidation. In a bear market, when prices hit rock bottom, just buy in and then hold for four years; in four years, it could quadruple.
Only buy Bitcoin and Ethereum, convert all cash to USDT, and that's it, hands in pockets, no one to love.
Long-term is definitely upward. However, the threshold is getting higher; now one Bitcoin is around 700,000 to 800,000, equivalent to a house in a third-tier city, which most people can't afford. That's why most people opt for altcoins.
In a certain sense, BTC definitely belongs to value investing!
